Essential Hadrian's Wall Facts
How Long? When? The most essential facts of the wall would be how long it is and when was it built. The 73-mile long wall was constructed in 117AD by Emperor Hadrian, to separate the Roman Empire from those northern Barbarians. In its glory, the wall was around 15 feet high and 10 feet wide.
Who actually built it? It took around 15,000 men over six years to build the wall. There were three main Roman garrisons stationed in England and Wales and all of these men were put to work building the wall. Hadrian himself had a keen interest in architecture and is thought to have designed it. At Chesters, you can see the names of the centurions who actually built the wall, carved into stone tablets.
How much of the wall still exists? Only around 10% of the original wall still remains. While much of the land is still shaped to accommodate the wall, the stone itself was re-purposed or buried after the wall was abandoned. Many local buildings are said to be built from the stone from Hadrian's Wall.
Is this the border between Scotland and England? No, it never was. It marked the border of the Roman Empire before they headed further north and created the Antonine Wall, before retreating back to the more secure Hadrian's Wall. Most of Northumberland, England's largest county, is north of the wall, so the wall definitely does not indicate the border.
